Study Summary
The purpose of this study is to identify differences in craniofacial morphology and tongue size between patients who have a history of difficult airway management and a control group of patients who had an uneventful airway management during induction of general anesthesia. In this study the investigators want to validate the hypothesis that there are craniofacial phenotypic differences between patients who have a history of difficult airway management and a control group of patients who have had an uneventful airway management during the induction of general anesthesia.
Primary Outcome
A curved low-frequency transducer and a Flex focul 400 ultrasound system were used to visualize the tongue and shadows of the hyoid bone and mandible. Midsagittal and coronal/transverse scans from the ultrasound were analyzed using ImageJ. The hyomental distances in the neutral and heal-extended positions were measured from the upper border of the hyoid bone to the lower border of the mentum. The ratio is defined as the ratio of the hyomental distance at the extreme of head extension to that in
